Support logical operator type inference with union type approximation#31
Conversation
Ruby's && and || are short-circuit operators that return one of their
operands rather than a boolean. Since we cannot determine truthiness
at static analysis time, we conservatively model the result as a union
of both sides' types. This prevents false positives when methods are
called on the result of logical expressions (e.g. `("a" && "b").upcase`).
